I300M Irradiator
Bulb, Screen, and Reflector Maintenance
Cleaning Guidelines
At least every 500 hours of operation, the irradiator should be removed from the light
shield, and the screen, lamp bulb, and reflector inspected carefully. Clean as needed.
Instructions for removing and replacing these components appear later in this chapter.
Guidelines for cleaning these components follow.
If the reflector or bulb surfaces show signs of dirt, oil, or vaporized materials, they
should be removed and cleaned with a good industrial cleaner, using a lint-free cloth
or tissue. The cleaner should contain no waxes, silicones, dyes or perfumes. Simple
Green® and Windex® are recommended. Wipe away any residues, using the cloth or
tissue with pure water. Alcohol, isopropyl, or methanol may be used for final removal
of residues, except when alcohol is not allowed as a solvent.
If deposits on the screen, bulb, and reflector are consistently found at 500-hour
inspections, the blower filters should be changed more frequently, or a more efficient
filter should be used. These deposits can cause premature failures when particles burn
into the quartz lamp or result in dulling of the reflectors.
Bulb Cleaning
Handle bulbs with a lint-free cloth or tissue taking care not to leave fingerprints.
Baked-on material can be removed from bulbs with a MILD abrasive cleaner such as
Soft Scrub®, followed by a thorough rinse with water. If alcohol is allowed, do a final
wipe with alcohol. Harsh abrasives and steel wool should NEVER be used on bulbs.
Reflector Cleaning
If the reflector surface is dull or discolored, it should be cleaned. Abrasives should
never be used on reflectors.
